That was some pretty snotty stuff Democratic operative Kathy Groob tweeted this weekend about former Labor Secretary Elaine Chao, and Ms. Groob knows.

Caught between her rock-hard party loyalty and a truly hard place, Ms. Groob deleted her Twitter account after coming under heavy fire for tweeting that Ms. Chao, wife of Senate Minority Leader Mitch McConnell, Kentucky Republican, “isn’t from KY, she is Asian.”

Welcome, Dear Readers, to post-racial America, where playing the race card is as bigoted as Jim Crow cards on water fountains.

Liberals and progressives changed horses.

Post-civil rights movement, blatant, overt bigotry — racial, religious, ethnic or otherwise — was a no-no. And the bra-burning crowd raised so much Cain you would think Wonder Woman is now disguised as Hillary Clinton. (Ha, ha.)

We’ve even got liberal think tanks telling us that poor little black boys and girls would be better off if their teachers were all successful black men and women.

Oh. I see.

That’s why Asian students haven’t fallen into the academic gap.

There are soooo many Asian teachers in American classrooms they have plenty to emulate, an endless stream from which to choose as many or as few role models as they’d like.

Of course, that’s not exactly what a study by the Center for American Progress says.

What the study says is that little black boys and girls don’t have enough teachers who look like them and that there is a large demographic mismatch between students and teachers of color.

“This matters because students of color need teachers who not only set rigorous standards for them but teachers who also can provide models of professional success,” CAP says on its website. “Teachers of color have demonstrated success in increasing the academic achievement of students of similar backgrounds.”

Now, my intent is not to belabor an earlier point, but that “similar backgrounds” thing does not explain how Ms. Chao rose to become our Labor Department chief any more than it explains why Ms. Groob chose Isaac Mizrahi pink for the jacket of her book “Pink Politics: The Woman’s Practical Guide to Winning Elections.” Besides, pink is such a girly-girl color.

And it certainly doesn’t explain why even Wikipedia seems to be in on “similar backgrounds” game of post-racial America.

Is Wiki pre- or post-?

If you’ve ever popped into Wikipedia to peruse someone’s biography, you’re likely to see a section labeled “early life” or “personal” or something to that effect. Well, signs of pre-racial America is in the details.

Wiki points out that and Jon Voight’s paternal grandfather and his paternal grandmother’s parents were Slovak immigrants from Hungary and his maternal grandparents’ family were German immigrants.

Wiki also details Jon Bon Jovi’s ancestry: “His father was of Italian (from Sciacca, Sicily) and Slovak ancestry and his mother is of German and Russian descent. He has stated that he is a blood relative of singer Frank Sinatra.”

How does Wiki handle the two Robert Griffins?

It offers no similar race or ethnic details for former Baylor QB Robert Griffin or former Baylor offensive lineman Robert Griffin, the one who’s not famously known as RG3.

Welcome to post-racial America?

Or is Wikipedia racist?

Both Jons are of European descent, while both RGs are Wiki doesn’t say.

Black.

The big-bang theory regarding “post-racial” America is imploding.

Not every American was happy and singing and making merry like Christmas (a tribute to Maya Angelou) when Barack Obama was elected in 2008 to roost the White House.

For sure, he tried to earn his votes by insistently proclaiming, “Yes We Can.”

And, yes, Americans did.

Elderly and millennial voters, white and black voters, independent, Democratic and Republican voters joined hands and pushed Mr. Obama into the White House.
